Abstract

Three heats of 0. 20C-13Cr turbine blade steel with 0. 06, 2. 77, and 1. 04%Mo were investigated. Tests under fatigue stress in aqueous NaCl solutions at 20 to 200 C, and a second series of tests without mechanical stress above 150 C in autoclaves, are described in detail. The results show significantly improved corrosion fatigue strength in the 1%Mo steel but no effect of the carbides present. At 150 C, at over 10**6 stress reversals, severe corrosion was observed even with low NaCl concentration. Tests at this temperature and loads betwen plus or minus 150 and plus or minus 200 N/mm**2 are considered most closely representative of service conditions.
